Current loop Output

The CURRENT

Current loop Output LOOP terminals have not polarity.

Shield

The current loop output has not polarity.

Use an external DC current source.

Connect the FG terminal when using the shield cable.

8.3.2.Communication Modes

There are the following modes.

Stream Mode

The data is output at every update of display. If the data can not output due to slow baud rate completely, data is output at next update.

Auto Print Mode

The data is printed at batch finish and recipe finish automatically.

Manual Print Mode

When the preset print key or terminal is pressed, data is output.

Accumulation Print Mode

When accumulating it or canceling the last result, the result of batch finish and recipe finish is printed. When canceling the last result, the inverse polarity data is output.
